There should be a block that is like an extended version of the Shop Block. In addition to the mushroom, flower, cape, and star, you can buy 1-ups and Yoshis. Of course, in the case of 1-ups, you would probably need an alternate coin counter, such as the 6-digit coin counter patch, but I think it would be a good idea nevertheless.
